Let f(x) = (x – 2)2 and g(x) = 4 – x2.
A) Find the points of intersection.
B) Find the area bounded by the curves.
C) Find the volume of the right cylinder with base bounded by f(x) and g(x) and height 6.
D) Set up an integral for the volume of the solid formed when the region is rotated about the y-
axis.
E) Set up an integral for the volume of the solid formed when the region is rotated about the

G) Set up an integral for the volume of the solid with base on the xy plane, bounded by f(x) and
g(x), and cross-sections perpendicular to the x-axis isosceles right triangles, with hypotenuse on
the xy plane.
H) Set up an integral for the volume of the solid with base on the xy plane, bounded by f(x) and
g(x) with cross-sections perpendicular to the Y axis semicircles. You must set this up as a y-
integration.
